Title: Monolithic piezo-electric bimorph and manufacture thereof
Inventor: ARAN JIYON MAIKERUZU
IPC: H02N2/04
Filed: 1988-09-19
Abstract: PURPOSE: To obtain high resistance to mechanical destruction by simultaneously impressing a polarization electric field across the thickness of a sheet having a direction and size selected so that a layer in a further high temperature can be polarized to an opposite direction to a first polarizing direction, and a layer in a further low temperature can be held to the first polarizing direction. CONSTITUTION: A polarization electric field is removed, and temperature controllers 17 and 19 are operated for setting the temperature of an electrode, and applying linear temperature gradient to a sheet 10. Especially, the temperature of an upper electrode 16 is increased to a relatively high level below the Curie temperature, and the temperature of a lower electrode 18 is held to be lower than the Curie temperature. Then, a polarization electric field in an opposite direction shown by an arrow 28 is impressed to electrodes 16 and 18, and the intensity of this opposite electric field is selected so that a material present in the middle of the sheet 10 can be depolarized. This is attained by selecting an electric field almost equal to the forced electric field of the material in the temperature of the intermediate part of the sheet 10.  Thus, high mechanical resistance can be obtained, and simple and high speed manufacture can be attained.

Title: Processing system in error occurrence
Inventor: KUBOU KATSUMI
IPC: G06F11/32
Filed: 1982-12-29
Abstract: PURPOSE:To match continuously an FF for error control and an FF for error display with each other by supplying the output of a checking circuit to the FF for error control and also supplying it directly to the FF for error display. CONSTITUTION:The FF3 for error display and the FF4 for error control are both reset. The checking circuit 2 outputs an error signal with logic 1 when detecting error occurrence. When a signal CLOFF has logic 0, a clock signal CLKA is generated. This signal sets the error signal with a logic 1 to the FF3 for error display and also sets the error control FF4 at the same time. When the FF4 is set, a signal ERR1 has logic 1 and the signal CLKA is ceased, so that the contents of a register 1 shows the error occurrence continuously.
